Where can I submit request for new features in the C# language?

Question

I know Microsoft has a forum similar to uservoice.com for feature and bug submissions, but it has slipped my mind and my google-fu is fail this afternoon. Then I thought... hey, what a great question for Stack Overflow! So:

Where can I go to submit official requests for new features of the C# language?

Answer 1

GitHub Issues:

• C# language
• VB language
• C# cross cutting VB
• Roslyn discussions on the Rosyln compiler (only)
• CoreFX This includes things like System.Collections, System.IO for .NET Core (.NET Core 2.0)
• CoreCLR This covers RyuJIT, GC and mscorlib for .NET Core (.NET Core 2.0)
• ASP.NET Core This is for ASP.NET Core (.NET Core 2.0)
• ASP.NET 4.7 - unknown

Historical places not for current discussion:

• Roslyn C# Language Design forum
• Roslyn discussions on C# 6.0, C# 7.0 and beyond

There is also the Visual Studio Uservoice for requests pertaining to Visual Studio specifically

Here is the official user voice channel for suggestions and ideas on the C# language.
